Are you still getting raid bosses? Make it 5 out of 6 here (finally got SG before going to sleep after the new reissue update). Lol.
I only have to roll 18x (haven't gotten the last bloom), so it's not much of a stress for me now. I just need 5x ?-8 runs and 4x SG Advanced for those 18 rolls and I should be done with the gacha. I was lucky to get each bloom in Rounds 2, 4, and 6 in <5 rolls, so there's that.
At this juncture of the event, once the special item drops, just skip everything else if the rolls are going nowhere.
